KeyStore Explorer: A great tool for simplifying cryptographic tasks in Java.

Recently I have been testing this tool when I work with Java Key Stores or Trust Stores. It’s KeyStore Explorer.

You can always use command line to execute cryptographic tasks in java using keytool library or bouncy castle, however for many daily activities like generating CSR files, creating cryptographic keys or managing several keystores or trust stores, you prefer a more friendly tool. This is where KeyStore Explorer fits in.

It’s support for cryptographic tasks, according to it’s website, is:

And you can handle, compare and manage many keystore files from the main window and explore their content easily:

It is definitely an extraordinary tool that can be downloaded here:
